The timing time of the deviation time calibration low-frequency oscillator differed between the poor correction reference time, i.e., by determining that accuracy is relatively low
Low-frequency oscillator timing time and the accurate and gap between the timing time of standard to the timing time of low-frequency oscillator
Precisely efficiently correct.
Further, in the above-described embodiments, calibration subelement 5084 is specifically used for：According to deviation time and error correction
Fiducial time calculates the timing error percentage of low-frequency oscillator；Low-frequency oscillator after by calibration carries out the process of timing
In, read the real-time timing time of low-frequency oscillator；Real-time timing time is calibrated according to timing error percentage.
In this embodiment, further can be according to the error correction fiducial time of standard and the current meter of low-frequency oscillator
When time and error correction fiducial time between the deviation time that differs determine the timing error percentage of low-frequency oscillator, then
, can be according to the timing error percentage by low-frequency oscillator during the low-frequency oscillator after by calibration carries out timing
Real-time timing time be scaled the timing time of standard, i.e., effectively and accurately complete the calibration to low-frequency oscillator timing,
So as to lift Consumer's Experience.
Further, in one particular embodiment of the present invention, if error correction fiducial time is 1 second, remote control
High-frequency generator and low-frequency oscillator built in control chip are interval with 1 millisecond while start timing, then work as the higher-order of oscillation
When the timing time of device reaches 1 second, resonance has been swung 1000 times, and because low-frequency oscillator timing uncertainty truly has error, then it is now
Only vibrate 900 times, i.e. the present timing time is 900 milliseconds, then deviation time is 100 milliseconds, and timing error percentage is
10%, if therefore only by low-frequency oscillator timing during, the real-time timing time of low-frequency oscillator is 9 seconds, then its is accurate
Standard timing time should be (9+9 × 10%) second.
Further, in the above-described embodiments, the control device 50 of remote control also includes：Second setting unit 510, such as scheme
Shown in 5.
Wherein, the second setting unit 510 is used to set wake-up period；And in alignment unit 508 according to error correction base
Between punctual and after the timing time of present timing time calibration low-frequency oscillator, control unit 504 is additionally operable to：High frequency is closed in control
Oscillator, so that remote control enters low power mode of operation；Restarting high-frequency generator is controlled according to wake-up period, makes remote control
Device switches to normal mode of operation by low power mode of operation, to recalibrate the timing time of low frequency vibrator.
In this embodiment, it is contemplated that the deviation time of the low-frequency oscillator timing determined during calibration can be by environment temperature etc.
Factor influences and changed, if follow-up missed using the timing being calculated according to the deviation time before not changing always
The real-time timing time of poor percentage calibration low-frequency oscillator can then influence the accuracy of calibration, therefore it is determined that low-frequency oscillator
Only it is in after timing error percentage and closing high-frequency generator, it is necessary to count by the remote control of low-frequency oscillator progress timing
The operating time of the low power mode of operation of power saving, and the operating time for being in remote control low power mode of operation reaches advance
During the wake-up period of setting, restarting high-frequency generator makes remote control enter normal mode of operation, to obtain low-frequency oscillator
New timing error percentage, and recalibrate according to the new timing error percentage timing time of low-frequency oscillator,
So move in circles, the accuracy of timekeeping of high-frequency generator is maintained at higher level, so that it is guaranteed that entering by low-frequency oscillator
The accuracy of row timing.
